xfs: remove all boilerplate defer init/finish code
At this point, the transaction subsystem completely manages deferred items internally such that the common and boilerplate xfs_trans_alloc() -> xfs_defer_init() -> xfs_defer_finish() -> xfs_trans_commit() sequence can be replaced with a simple transaction allocation and commit. Remove all such boilerplate deferred ops code. In doing so, we change each case over to use the dfops in the transaction and specifically eliminate: - The on-stack dfops and associated xfs_defer_init() call, as the internal dfops is initialized on transaction allocation. - xfs_bmap_finish() calls that precede a final xfs_trans_commit() of a transaction. - xfs_defer_cancel() calls in error handlers that precede a transaction cancel. The only deferred ops calls that remain are those that are non-deterministic with respect to the final commit of the associated transaction or are open-coded due to special handling.
